bad skin condition

Please throw light on my skin condition.Months back i had a red spot on my neck, not itchy but dry sometimes. After few days i developed similar spots (notr round & various shapes) on my hand, shoulders, lower part of the arm, armpits & later on my chest, abdomen, side & back.Later on they appeared on my thighs.These spots turned into more tan in color & are very itchy during night or when i sweat, specially in the abdomen & side area.They are very much dry in nature & after scratching they look like white as if dead skins will peel off. Scratching also peels off the dried skin from these patches.Also i have dry skin between by thumb fingers & dry spots on my palm. They sometimes also itch.After taking shower, & if i dont apply moistarizer things get worse & i feel that my skin may crack.Apart from this skin problem everthing like my food habits, etc are very normal.Is this related to STD. I am very worried, please help.Thanks to you all in advance.
